To have the relative value of each part easily discerned, the book of many parts should be planned before copy is given to the compositors, so that each part may be set in a proper size of type and with uniformity of style. It is understood by all parties that the text should be set in the larger and the adjuncts in smaller sizes of type, and that the size selected for each different part should be so graduated that the reader can determine at a glance its relative value, and that parts of equal importance should be, for the most part, of similar size and style of type.
